On equirectangular panoramas some lines are distorted and some aren't. Horizontal lines at the center are straight and so are all vertical lines. All other lines are more or less distorted. Lines closer to the top or bottom are more distorted than those near the center.

There is no way to show the entire panorama (as a single photography) with all straight lines - straight. But...Here comes the cubic perspective:

As you can see - with cubic perspective:

All lines are straight,

The panorama is showed with 6 different square photos. They are called "cubefaces" (because they can be arranged to make a perfect 3D cube).

Cubic perspective is better suited for fullscreen panoramic players but there is no easy way to make them. For example, I used 4 different apps for the examples above: autostitch, Perl/erect2cubic command-line tool, GIMP and hugin.

Anybody interested in a quick tutorial on how to make cubic panoramas?

In the last few weeks I became a big fan of a service called FriendFeed. FriendFeed is a personal feed aggregator. With FF you can have all your activities from various sites in one place. For example, all your Twitts, all your images on Flickr, all your blog posts -- all in one place. Other people can comment, and/or mark as "like" for your entries.

But it was not possible to have your own panoramas on FF. In fact, there wasn't a personal RSS feed on panoye.

But, from now on - your personal panorama-feed is online. The link is on every user's profile page:
